No true. The PARENTS who came over, uneducated and impoverished, and not even speaking the language, didn’t lift themselves out. But their CHILDREN did - the first in the family who didn’t have the advantages of coming from educated homes.
Yet they still managed to graduate from college, despite having all the disadvantages. What they DID have were parents who emphasized the value of higher education.
I don’t know why you find it so difficult to admit that Jews place a very big priority on education, and have for thousands of years. “Learning” is seen as a Mitzvah, in fact. And it’s the biggest reason that they lifted themselves out of abject poverty in a single generation, when they children became middle and upper-middle class: EDUCATION.
